Yoshimura Slip-On - R-11 Ninja400/250(18-22/23) (ST)

Fits: 2018-2025 Kawasaki EX400 Ninja 400

The Slip-On R-11 Cyclone for the Ninja 250/400 was developed to draw out the maximum styling and performance from these bikes. The refined R-11 silencer shape incorporates Yoshimura's race-bred know-how throughout, including lean-angle clearance, weight reduction and aerodynamics, while the sharp carbon end cap and lightened aluminium silencer stay further enhance the sporty styling.

Developed to balance ease of use with more power, it exceeds standard performance across almost the entire range with further gains from 7,500 rpm to peak. The compact R-11 achieves lower weight, controlled volume, quality sound and more performance, and is 43% lighter than the standard silencer on the Ninja 250 and 49% lighter on the Ninja 400 (compared with titanium Cover). The combination of added power and lighter weight improves performance in every situation, from commuting and touring to sports riding.
